Progress inches ever forward......

Almost all the components are now stuck down onto the winch deck, and, the first of the graphics applied to the hull. No, its not on backwards, the other side is ok!

Need to order some more names, I ordered the wrong size first time..doh!

Looking excellent Ian, as usual.

Do you know what you are going to build next ?

Next build?  Blimey, wanna finish this one first, its taken forever!

Having said that, I am working on something, but it's staying under wraps for the moment as I am still developing the design.

Sorry Ian, was just wondering what you could build next that could be more unusual than your recent boats.

I think I will be hard pushed to come up with something more unusual, however, the project under development is a little unusual and differs from the norm.

Took the plunge - literally, today and chucked Orca into the external test tank.

She floats and is stable - what a relief!  %%

She has 7kg lead ballast in her, plus a 12v 4a lead acid battery.

Sitting just a fraction high maybe, but there are no fittings on her at the time of the test, so, she should be about right !

Hi Ian

Looking really good. :-))

Now you have her wet I was just wondering about something general to models not to yours in particular.
I see you have the battery and some lead in her - I'll assume it is all as low down as possible too. If all the
weight is very low and I suppose it is often centralised  too - I can see that gives maximum stability, but will
a model not look a bit rigid too? righting itself too quickly. I don't think I have said that very clearly. I just
happened to be looking at some fore and aft ballast tanks on the old Peralta ferry hence the line of thought
arising. What do you think? Do you ever move weight about?

Here we have the trolley, complete with nose pad!

The more observant amongst you will note its angled, there are reasons:
1: so I know which is the front
2: so it wont fall off the back
3: the water at my club has a launching ramp and the idea is that the boat will enter the water stern first more or less on an even keel.

Regarding ballast, yes its all as low as possible, but not all centralised, there are some lumps of lead that go over towards the sides, evenly about the centre line. Three reasons:
1: couldn't get it all on the centreline
2: seems the right thing to do
3: real ships don't have all the ballast on the centreline, so I guess it must be ok.

Hooray,

I worry about the larger size.  %)

Hello Umi

The L and M looks strange for the bottom part ...

Might be just the angle on the frames.

Hi Umi
I'm happy to see this ;-)

But Xtian is right...
Maybe you have to "fill up" the L and M to get a clear stringer line between Bow and middle part.

@Ian
Have you ever thought about some air-filled wheels instead of theese small hard rubber wheels?
It is much easier to run with big wheels, even on bad lanes or grassland.
(and its more gentle to the model...)

Peter,

Yes, air tyres have been a consideration, but, at the moment its not a problem. I can park within 50m of the lake and its all tarmac. However, I may swap at some time cos you are right they are easier on the model even on good surfaces.

Also, they float! The frame is v light - aluminium.

I don't know if it would work or not maybe you can fill a portion of the tires with water. This would help some weight into the tires to help them not to float when putting the transport frame into the water. To puit the water in you would need to remove the valve from the stem put in some water and then fill with air.

Hmm...
That's right, they are floating....
That has never been a problem to me, cause my home club has no slipping ramp.

My trolley was buildt as a wodden toolbox. No chance to slip it into the water....
